A member of Pegasus Gymnastics Club in his home town of Maidstone, Kent, Courtney Tulloch started gymnastics aged six and burst onto the scene as part of the Team GB squad at the 2011 European Youth Olympic Festival in Turkey, taking home team and rings gold.
The following year he won rings and team gold at the 2012 European Juniors before winning the same medals at the Australian Youth Olympic Festival the following year.
The Lewisham-born gymnast tasted his first senior success at the 2013 World Cup in Ljubljana on his favoured rings event by winning silver.
Tulloch represented Great Britain at the 2014 World Artistic Gymnastics Championships in Nanning, China and helped the team reach the final as well as finishing fifth in the rings final.
His first major senior medal came at the 2016 European Championships in Bern as Great Britain scooped silver in the team final. That success was added to a year later in Romania by winning individual silver in the rings final.
